Description

Chassis flow resistance adjustment structure

The present invention relates to the technical field of a heat dissipation airflow guiding structure of a chassis, and in particular to a chassis flow resistance adjusting structure for adjusting the flow resistance of each partition space in the chassis so that the heat dissipation airflow can flow evenly in each partition space.

Computer equipment includes circuit boards and multiple electronic components. When the electronic components are running, they will generate heat, causing the temperature of the electronic components themselves to rise. The increase in the temperature of the electronic components will affect the operating efficiency of the electronic components. Therefore, airflow must be provided in the chassis for heat dissipation.

Computer equipment, especially servers, include a main circuit board and multiple electronic modules. Each electronic module has its own circuit board. Therefore, the overall configuration in the chassis will form multiple partitions. The heat dissipation airflow must flow evenly through each partition to dissipate heat for each electronic module. However, each electronic module has electronic components of different numbers and shapes. Therefore, each partition will produce different flow resistances to the heat dissipation airflow. In this way, when the heat dissipation airflow passes through each partition, the heat dissipation airflow in each partition will be uneven. In particular, electronic modules with a large number of electronic components have a large flow resistance to the airflow, so the flow rate of the heat dissipation airflow will be reduced. However, electronic modules with a large number of electronic components have a large amount of heat generated, so they need a larger flow rate of heat dissipation airflow, which results in poor heat dissipation.

In view of this, the purpose of the present invention is to provide a chassis flow resistance adjustment structure, which can increase the flow resistance of the partition space with smaller airflow resistance to prevent a large amount of heat dissipation airflow from entering this partition space, so that other partition spaces with larger flow resistance can obtain heat dissipation airflow with sufficient flow, thereby solving the problem of poor heat dissipation caused by insufficient flow of heat dissipation airflow.

An embodiment of the chassis flow resistance adjustment structure of the present invention is located in a chassis and is arranged on a supporting bracket of an electronic module. The supporting bracket divides the chassis into a first space and a second space, and the heat dissipation airflow flows through the first space and the second space at the same time. The chassis flow resistance adjustment structure of this embodiment includes: a handle, a buckle, and a flow resistance adjustment member. The handle is rotatably arranged on the supporting bracket and is located in the first space. The handle can be rotated between a release position and a buckle position. The buckle is arranged on the handle and can move between a locking position and a retreat position in a direction parallel to the handle. When the handle pivots from the release position to the lock position, the buckle first abuts against the side wall of the bracket and moves to the retreat position. When aligned with the locking groove of the load-bearing bracket, the buckle moves to the locking position to lock the locking groove, so that the handle is positioned at the lock position. The flow resistance adjusting member is arranged on the handle and is flush with the edge of the handle. The buckle blocks the flow resistance adjusting member. When the buckle moves to the retreat position, the buckle releases the flow resistance adjusting member. The flow resistance adjusting member can move in a direction perpendicular to the handle and protrude from the handle to adjust the flow resistance of the first space.

By arranging a flow resistance adjusting piece on the handle piece of the supporting bracket and arranging a suitable mechanism on the handle piece for locking the handle piece to the buckle of the supporting bracket, the flow resistance adjusting piece can move along with the movement of the buckle and protrude from the handle piece during the process of the buckle moving and buckling on the supporting bracket, thereby generating greater resistance to the airflow flowing through the first space, so as to adjust the airflow rate flowing through the first space and the second space.

Please refer to the first and second figures, which show an embodiment of the chassis flow resistance adjustment structure 2 of the present invention. The chassis flow resistance adjustment structure 2 of this embodiment is located in a chassis 1 and is set on a support bracket H, and the support bracket H is used to support an electronic module E. The support bracket H has two opposite and parallel side walls H1, a main circuit board C is set between the two side walls (not shown) of the chassis 1, and the support bracket H is also set between the two side walls (not shown) of the chassis 1 and located above the main circuit board C. The support bracket H divides the inside of the chassis 1 into a first space S1 and a second space S2. The first space S1 is above the support bracket H. The electronic module E is set on the support bracket H and is located in the first space S1, and the main circuit board C is located in the second space S2. The heat dissipation airflow generated by the fan (not shown) flows through the first space S1 and the second space S2 at the same time.

The chassis flow resistance adjustment structure 2 of this embodiment includes a handle 10, a buckle 20 and a flow resistance adjustment member 30. As shown in the second figure, the handle 10 is used for a user to hold and carry the electronic module E. The handle 10 is rotatably disposed on the support bracket H and is located in the first space S1. The handle 10 can pivot between a release position and a buckle position.

Please refer to the third, fourth and fifth figures together. The handle 10 includes an operating crossbar 11 and two hinge portions 12 disposed on opposite sides of the operating crossbar 11. The two hinge portions 12 extend away from the operating crossbar 11 and are rotatably connected to the support bracket H.

The operating crossbar 11 includes a front component 111, a rear component 112, and a structural reinforcement component 113 disposed between the front component 111 and the rear component 112. The front component 111 includes a top wall 1111, a bottom wall 1112, and a front side wall 1113. The top wall 1111 and the bottom wall 1112 become the top wall 11a and the bottom wall 11b of the operating crossbar 11, and the front side wall 1113 becomes the first side wall 11c of the operating crossbar 11, and the first side wall 11c is located at a side away from the electronic module E. The operating crossbar 11 further includes a slide trough 114, and the buckle 20 is movably disposed in the slide trough 114. The slide chute body 114 includes two guide side walls 1141, a first supporting side wall 1142 and a second supporting side wall 1145 which are arranged opposite to each other. The first supporting side wall 1142 and the second supporting side wall 1145 are arranged opposite to each other. The latch 20 is carried on the top edges of the first supporting side wall 1142 and the second supporting side wall 1145 and abuts against the guide side wall 1141.

The buckle 20 is disposed on the handle 10 and can move between a snap-in position and a retreat position along a first direction L1 parallel to the handle 10. The buckle 20 includes a buckle body 21, a buckle portion 22 and a stop bearing portion 23. The buckle body 21 is disposed in the slide chute 114 and moves between a snap-in position and a retreat position along the first direction L1, and the first direction L1 is parallel to the extension direction of the first side wall 11c. The buckle portion 22 and the stop bearing portion 23 are respectively disposed on opposite sides of the buckle body 21. The first bearing side wall 1142 of the chute body 114 has a notch 1143, and the buckle portion 22 moves from the notch 1143 to protrude from the chute body 114 or enter the chute body 114. The stop bearing portion 23 is straddled on the second bearing side wall 1145 and extends in the opposite direction to the outside of the chute body 114. An opening 11e is respectively provided at the left and right ends of the operating horizontal lever 11, and the buckle portion 22 can protrude from the operating horizontal lever 11 through the opening 11e or be pushed to enter the operating horizontal lever 11 through the opening 11e. When the buckle body 21 moves to the engaging position, the buckle portion 22 protrudes from the opening 11e on the operating horizontal rod 11. When the buckle body 21 moves to the retreating position, the buckle portion 22 is pushed into the operating horizontal rod 11 through the opening 11e and retreats into the slide groove 114.

The flow resistance adjustment structure 1 of this embodiment further includes a return elastic member 40, which is disposed in the slide groove body 114 and has two ends respectively abutting against the buckle body 21 and the second supporting side wall 1145 of the slide groove body 114. The return elastic member 40 applies force to the buckle body 21. When the handle 10 is rotated from the release position to the lock position, the buckle 20 is pushed to the retreat position due to interference with the side wall H1 of the supporting bracket H, and the return elastic member 40 is deformed. When the handle 10 continues to rotate until the buckle 20 is aligned with the engaging groove H2 of the side wall H1 of the support bracket H, the force applied by the resetting elastic member 40 to the buckle body 21 causes the buckle 20 to move to the engaging position to engage with the engaging groove H2, so that the handle 10 is positioned at the locking position.

Referring to FIG. 6 , the stopper bearing portion 23 has an upper surface 231 and a lower surface 232 disposed opposite to each other and a through groove 233 passing through the upper surface 231 and the lower surface 232 . A first inclined surface 234 is formed at the end edge of the through groove 233 adjacent to the lower surface 232 of the stopper bearing portion 23 .

Please refer to the third, fourth and fifth figures together. The flow resistance adjusting member 30 is disposed on the handle member 10 and is flush with the edges of the top wall 11a and the bottom wall 11b of the operating horizontal lever 11 of the handle member 10. The flow resistance adjusting member 30 is movably disposed on the first side wall 11c. The flow resistance adjusting member 30 includes a fluid blocking plate 31, a pair of stop pins 32 and a push plate 34. The fluid blocking plate 31 abuts against the first side wall 11c. The first side wall 11c has a pair of first slots 11g and a second slot 11h. A pair of stop pins 32 and a push plate 34 extend from the fluid blocking plate 31 through the first slots 11g and the second slots 11h respectively and enter the interior of the operating crossbar 11, wherein the stop pin 32 abuts against the stop bearing portion 23. The stop pin 32 has a second inclined surface 321 at a position corresponding to the first inclined surface 234 of the through slot 233.

Please refer to FIG9 and FIG10 together. The chassis flow resistance adjustment structure 2 of this embodiment further includes a biasing elastic member 50. The biasing elastic member 50 is disposed between the handle member 10 and the flow resistance adjustment member 30. One end of the biasing elastic member 50 abuts against the top wall 11a of the operating crossbar 11 of the handle member 10, and the other end of the biasing elastic member 50 abuts against the push plate 34.

Please refer to FIG. 7 and FIG. 8 , the first slot 11g and the second slot 11h extend along a second direction L2, and the second direction L2 is perpendicular to the first direction L1. Therefore, when the user rotates the handle 10 to move the handle 10 from the release position to the locking position, the buckle body 21 moves from the locking position to the retreat position, and the stop bearing portion 23 moves relative to the stop pin 32 until the stop pin 32 is aligned with the through slot 233 of the stop bearing portion 23, and then the stop pin 32 passes through the through slot 233 and moves downward from the upper surface 231 of the stop bearing portion 23. The fluid blocking plate 31 moves away from the stop bearing portion 23, so that the fluid blocking plate 31 moves downward along the second direction L2, as shown in Figures 9 and 10. At the same time, the force exerted by the biasing elastic member 50 on the push plate 34 will also reliably move the fluid blocking plate 31 downward, and then the buckle body 21 moves from the retreat position to the engagement position, so that the stop pin 32 is stopped on the lower surface 232 of the stop bearing portion 23. At this time, the fluid blocking plate 31 protrudes downward from the bottom wall 11b of the operating horizontal lever 11 of the handle member 10, so that the operating horizontal lever 11 forms a larger cross-sectional area than the first side wall 11c, so that when the heat dissipation airflow flows through the first space S1, the large-area operating horizontal lever 11 provides a larger flow resistance. By moving the fluid blocking plate 31, the flow resistance of the first space S1 can be adjusted.

When the user wants to carry the electronic module E, the user applies force to push the fluid blocking plate 31 upward, so that the second inclined surface 321 of the stop pin 32 abuts against the first inclined surface 234 of the stop bearing portion 23, and then the relative movement between the second inclined surface 321 and the first inclined surface 234 moves the latch body 21 from the engaged position to the retreat position until the stop pin 32 is aligned with the through groove 233 of the stop bearing portion 23, so that the stop pin 32 passes through the through groove 233 and returns to the upper surface 231 of the stop bearing portion 23 and stops on the upper surface 231. At this time, the fluid blocking plate 31 returns to a state flush with the top wall 11a and the bottom wall 11b of the operating crossbar 11, and the user can pivot the handle 10 to move the handle 10 from the locking position to the releasing position, so that the user can remove the electronic module E from the chassis 1.

By arranging a flow resistance adjusting member on the handle member of the supporting bracket, the flow resistance adjusting member can move along with the movement of the buckle member and protrude from the handle member during the process of the buckle member moving and buckling on the supporting bracket, thereby generating greater resistance to the airflow flowing through the first space, so as to adjust the airflow rate flowing through the first space and the second space.
